Application filed. July 3, 1911. Serial No. 636,720.

To all whom it may concern:

lie it known that I, GUsTAr BERGMAN, a citizen of the United States, residing at Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Lasting-llfaohines, of Y which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and more particularly to lasting, machines of the bed type which employ end lasting mechanisms for the toe and heel.

The present invention, as embodied in a machine of the said type, comprises various improvements in the organization and construction of the toe and heel lasting mechanisms, suggested by practical experience in the use of a machine of this type, as well as in the actuating mechanisms therefor.

It also includes newand improved retarding means for cooperating with the toe wipers and a novel hold down for clamping the shoe and last upon their supporting means together with the provision ofnovel means for supporting the toe and heel ends of a last. p

A feature of thetoe lasting mechanism consists in the provision of a. carrier for the toe wipers mounted for bodily movement upwardly for imparting upper stretching movement to the wipers and forwardly for carrying the wipers intoposition for the overwipe and, conveniently, means areprovided, arranged to be actuated by this forward movement of the wiper carrierto close the wipers for overwiping the upperinto lasted position. b This mounting of the wipers is strong and efficient and less complicated than the organization of similar mech-.

anisms in machines heretofore used.

F or operatlng the toe wiper carrier and toe wipers for the updraw and overwipe, in

accordance with an important feature of this invention, a single means is provided comprising preferably an eccentric or a cam arranged for continued movement to operate the carrier upwardly and forwardly to produce the updrawing and overwiping movements of the toe Wipers and for thereafter pulling the said wipers downwardly for compressing and compacting the over lasted upper upon the innersolei The illustrated construction is suchthat a single train of mechanism operates the wipers for their variouslastin'g movements and, preferably, the toe wipers during all their movements are positively actuated.

Highly important features of this inventlon consist in various improved arrangements for enabling the position and action of the toe wipers to be adapted readily to lasts of varying sizes and shapes. It is essential that the closing action or throw of the toe wipers shouldbe varied for lasts of different widths and a characteristic of the illustrated embodiment of this invention is theprovision of convenient means for ad- ]u'sting the eccentric or cam bodily for varying the throw of the wipers as desired. Preferably, however, the various subsidiary adjustments of the toewipers areeifected initial position below the plane of the shoe bottom, are closed in this positioning movement, the position of each wiper relatively to the'adjacent edge of the last is determined by the position relatively to the median line of the machine occupied by the said adjacent edge of the last, the said movable member as soon as one of the wipers engages the adjacent edge of the last being thereby shifted through suitable connections to cause the other wiper to be at once cor-i rectly positioned with regard to the last edge adjacent toit. Thereafter, in accordance with another feature of the invention, the said member is automatically locked in adjusted position, insuring that the position- I ingof the toe wipers thus obtained will be maintained during their subsequent overwiping action.

Other features of the invention include the provision of novel means for enabling lie vas

carrier to permit the plane of the acting faces of the wipers to coincide with the plane of the forepart of the last, irrespective of the roll or angular position thereof.

In accordance with a still further feature of the invention means are provided through which pressure may be applied to the ends of the toe wipers to enable the wipers during their downward compressing movement to crowd the upper hard upon the sole and to. compact it in lasted position. Preferably, also, provision is made for imparting a yielding quality to this downward compacting movement of the wipers.

In accordance with 'a further important feature of my invention, novel retarding means are provided for cooperating with the toe wipers. These means comprise preferably a yielding member adapted to be brought by manual means into engagement with the upstanding upper at the end of the toe to hold the upper upon the wipers during the updraw, and an associated plate arranged to engage the upper at the corners of the toe. This latter member is unyielding and serves as a stop for limiting the movement of the yielding member. The yielding member engages the upper with spring pressure and during the updraw the pressure of the said yielding member is auto- 1 matically increased by CO11P1'GSS1OI1 of its spring. Thereafter, during the overwipe, the corner plate acts as an auxiliary retarder to reduce the undesirable fullness of the upof the inward or closing movements of the wipers so that during the overwipe the wipers Have a forward drawing effect upon the vamp.

Still other means for jacking the shoe at the toe and heel and for independently securing the toe and heel supports in any desired position. A novel hold down is also provided, arranged to be brought into clamping engagement with the sole by treadle controlled means arranged so that the pressure exerted by the hold down can be varied at will and the hold down then secured in engagement with the shoe.

The heel lasting mechanism has in addi-' tion to features common to it and to the toe lasting mechanism, improved means for causing the heel supporting band to be conat the sides of the toe produced by the features comprise improvedtrativeembodiment of the invention shown in the drawings, and will then be clearly defined in the appended claims.

Referring to the drawings: I Figure 1 shows a machine illustrating one embodiment of my invention; the machine being shown in side elevation; Fig. 2 is a top plan view of the toe lasting mechanism and associated parts, showing the position of the wipers and of their actuating mechanism at the conclusion of the overwipe; Fig. 3 is a detail in side elevation, partly in section, showingthe position of the retarding devices prior to the updraw; Fig. 4 is a similar detail in side elevation, showing the position of the parts at the conclusion of the u-puraw; and Fig. 5 is a top planview, similar to Fig. 2, of the heel lasting mechanism.

The machine illustrated'in the drawings as embodying my invention comprises a bed or frame 2 supported by standards 4. The bed 2 carriesin addition to shoe supporting means and associated parts for effecting the j aching of the shoe, the end lasting mechanisms for the toe and heel.

The toe lasting mechanism shown at the left of Fig. lis carried by the toe head 6 slidably mounted in ways upon the bed'2. The heel lasting mechanism shown at the right of Fig. 1 is carried by a heel head 8 similarly mounted in the said ways. For adjusting the heads 5 and 8 toward and from each other, adjusting screws 10 and 12 are threaded through blocks 1% and 16 of the heads 6 and 8, hand wheels 18 and 20 being provided for turning the said screws foradjusting the respective heads longitudinally of the machine. By means of these adjusting devices, the toe and heel lasting mechanisms can be moved with relation to one another longitudinally of the machine to adapt the said mechanisms for operating upon shoes of all lengths as well as for operating upon shoes having long or short toes or prising thin plates 36 (Fig. connected to the frame of the l2 2) formed between the rectangulaiportion 26 of bar 9i, and its rounded end.

528. The other end of the bar has a similarl reduced androunded end (Fig. 2) which. extencs through a bearing block 46 restrained from lengthwise movement relatively to the bar B l by a pm l7 and asquare The block 46, in is thus ourshoulder ll) on th 2.11. which the endw-l of the bar naled. is )ivotall'v connected at Fl 1 to an upstanding link 50, the lower end of which carries a pin standingiin an elongated upright slot 52-. in the toe headframe 6. The bar 2 is thus arranged to have bodilymovement longitudinally of the machine in a substantia ly horizontal plane by reason of its aforesaid connection with the uprights 3G mounted for swinging movement abouttheir axis 38, and by reason of the pivotal'connections at 4:53 and 52 ot the bearing block 46 and the SHIHJOIUIIQ link 50.

also capable of being tipped about the pivot 52 as an axis up and down movement ofxthe it'orward end 44- of the said bar and its supporting link 50 being permitted by reason of the vertical slot These movements of the bar 9i actuated by mechanism hereinafter described. serve to im )art the undraw and closing or overwiping movements to the toe wipers in manner now to be explained.

The toe wipers 5% are of suitable forinto embrace the toe end of the last for working the upstanding margin of upper material into lasted position and are pivoted at their mner or rear ends to the rounded end llof the bar at 56.

T he forward or outer ends of the wipers 5-15; have pin and slotsiupporting and operating connections at 58 (Fig. 2) with arms:

60 of levers 62, the levers 62 being crossed at ca and there portion 26 of the carrier bar 24:. The wipers are thus mounted to be moved forwardly by the forward or endwise movement of bar 24: and means are provided arranged to be actuated by the said movement of bar 24 to close the wipers to overwipe the upper into lasted position, To this end the rear ends of the lovers 62 are provided with cam slots (35 in which stand cam rolls 66 on a cam roll carrying bar (38 extending transversely of the machine through a slot in the part 26 of bar Set. The cam roll carrying bar 68 is restrained from movement lengthwise of the machine by upright guides 70 (Fig. ;1) so cured to the toe head 6 and having forked upper ends which embrace the said bar 68 and permit it to move up and down therein 1), pivotally' said head at. .38 to permit tipping or swinging move- The bar is plane of the shoe bottom the said bar about its axis 32.

- ward movement of bar the trout ends of-the wipers 54, supporting a are provideth the rear ends of these and compact the overlasted margin of pivoted to the rectangular with the updraw movementsof the bar 24. From this construction it will be apparent that upon forward movement of the carrier bar 2+trand of the levers 62 which, as above stated, by reason of their connection at 64 with the bars 24 are necessarily carried tor- 'ardly with the said bar the cam rolls 66 being stationary relatively to the outwardly and baclm'ardly inclined cam slot Gal, will force the rear ends of the wiper closing leversto approach, and consequently the for ward ends ofthe wiper closing'levers will be moved toward oneanother like the blades of a pair of shears. This closing or shearing together of the front ends of the levers 1'52 induced by the forward movement of the,

,bar 24- operates to swing the front ends of the wipers 54: inwardly for overwiping the upper into lasted position, the shoe being su iported bottom upward in position for the operation of the wipers thereon.

In addition to the closing or overwiping movements of the wipers, the wipersfihave imparted to them uodraw movement for tensioning andstretchin the upper prior to overlaying it in lasted position. l'his moveinent of the wipers, like their closing oroverwiping movement, is effected by bodily movement of the wiper carrier 24:, the wiper carrying end of the bar 2i being swung in a direction substantially perpendicular to the through tipping of By reason of 24 at 56, the are lifted upward by the said up- 24; For supporting their connection with bar wipers 5-l arms 72 arms being secured tot-he bar 24 and the front ends of the said arms being supported between plates 74; bolted at 76 and 78 to the arms 60 of the wiping closing levers 62 and the said arms 60. The arms 72 enable a tirm downward pressure to be applied to the front ends of the wipersto pressdown upper, upon the sole and also relieve the joint of the wiper closing levers from excessive strain.

The above described updraw ,and overwiping movements of the wipers, which as above stated result from upward and forward bodily movements of the bar 24, are preferably actuated from an eccentric 80 (Fig. 1) fixed on a shaft 82 journaled in the upper ends of links 84 which are pivoted to the frame of. the toe head 6 at 85. Con reniently a handle 86 is provided for oper ating the eccentric 80 and shaft82, although it is obvious that power driven means may be supplied for this purpose, and that for the eccentric 80 a properly designed cam couldequallywvell besubstituted; lhe eccentric 80 as will be seen by reference to Fig. l is thus positioned to engage the under side it of the part 26 ofv the wiper carrier bar 24 for lifting the said bar and wipers 54: as above described for imparting updraw movement to the wipers.

For moving the bar 24: forwardly to cause the wipers to be moved into position for the overwipe and then for causing them to be closed for overlasting the upper, the eccentric lies in a forked bracket 88 (Fig. 1) on the supporting link 50, engagement of the eccentric 80 with the face 90 of the link 50 moving the bar 2% and wipers 54 forwardly for the overwipe through the block 46, and engagement of the eccentric with the arm 92 ofthe bracket 88 operating to move the carrier 84: backwardly and reversely into inoperative position to retard the wipers and to open them after the completion of the toe lasting operation.

After the overwipe of the upper into over lasted position, it is desirable that the wipers be actuated to apply downward pressure to the overlasted upper for compressing and compacting it in order that the upper may be laid snugly upon the sole in its lasted position. To accomplish this, the eccentric 80 is arranged to be brought into engagement with the top of the horizontal portion of the bracket 88 at the conclusion of the inward or overwiping movement of the wipers, thereby positively pushing the carrier 24: downwardly and causing the wipers to exert a strong downward pressure on the overlasted upper. In this connection it should be noticed that, by reason of the above described arrangement of the supporting arms 72, cross arms 60 and plates 7a, the wipers are caused to have a particuits shaft 82. Preferably, however,

larly efficient compacting action upon the upper through the application of pressure to their ends.

For enabling the throw of the wipers to be varied for adaptation to lasts of different widths, the eccentric shaft 82 lies in elongated slots 9& (Fig. 1) in the toe head frame 6, the said slots being formed to permit bodily adjustment of the shaft and eccentric in a horizontal direction lengthwise of the machine, the supporting links 84 having pivotal connections with the head 6 at 85 as described. Adjusting screws 96 supported in brackets 98 on the head 6 are threaded into lugs 100 on the links 84:. Rotation of the screws 96 in one direction operates to force the shaft 82 forwardly in its slots 9d, the eccentric 80 thereby through engagement with the face 90 of the link moving the bar 24 forwardly and the wipers inwardly for operating on'narrow lasts, and opposite rotation of screws 96 moving thebar 24 and the wipers reversely for operating on relatively wide lasts.

It will be observed that the above described adjustment of the wipers is effected by bodily movement of the eccentric 80 and the varicus other adjusting lasting devices are arranged to be effected independently of said shaft and eccentric and without disturbing their normal position.

As is well known in the art different lasts vary considerably in the amount of spring of their foreparts. Accordingly, it is essential for satisfactory work that convenient means be provided for adjusting the wipers quickly and accurately to cause the plane of their acting faces to coincide with the plane of the last bottom so that the wipers may overlay the upper evenly and snugly thereon. For so adjusting the wipers, the swinging uprights 36 have, as aforesaid, a series of pairs of opposite holes of which the opposite holes 34: are illustrated in Fig. 1 as having extended through them the pivot pin 32 which sustains the bearing block 30 in which is journaled the end 28 of the carrier bar 24. By adjusting the said pin into one or another of these pairs of holes the end 28 of the bar 24 can readily be moved upwardly or downwardly, thereby changing the inclination of the plane of the acting faces of the wipers to conform to the spring of any last.

Provision is also made for adapting the wipers for operating on lasts of crooked or unsymmetrical formation. If the shoe to be lasted has a crooked last that is, if the median line of the forepart extends in a different direction from the direction of the median line of the heel part, it is obvious that as the wipers are closed, one wiper will engage the upper at the adjacent edge of the last before the other wiper engages the upper at the opposite edge'unless provision is made to obviate this difficulty. Accordingly the cam roll carrying bar 68 is arranged to be free to be moved transversely of the machine and shoe in its guides 70. Preferably, in accordance with this feature of my invention, an initial closing of the wipers is effected by movement of the handle 86 to cause the eccentric 80 to move the link 50 forwardly. During this initial positioning of the wipers, the wipers are moved from the open position shown in Fig. 3 inwardly until the edges of the wipers contact with the adjacent edges of the last. lVhenever, as the wipers are thus moved inwardly, one of said wipers is stopped by contact with the adjacent edge of the last s before the other wiper has engaged the op posite edge of the shoe. the bar 68 will be shifted transversely positioning the other wiper relatively to the edge of the shoe bottom adjacent thereto. Thereafter, it is desirable that the wipers should be held relatively to the edges of the shoe in their adjusted position. Consequently the bar 68 is preferably arranged to be automatically locked in adjusted posimovements of the toe lot of the machine, thereby tion after the initial positioning 1 of the wipers. For this purpose locking hooks or latches 102 (Figs. 1 and 2) are provided on the upper ends of rods104 guided in bosses 106 secured to the guides and extending through a transverse plate 108 which spans the frame of the head 6 and is secured thereto. These latches are formed with knife edges adapted to be brought into engagement with teeth 110 formed on the upper face of the cam roll carrying bar (58 early in the updraw movement by reason of the lifting. of the bar (58 by the carrier 24 as the said carrier is moved upwardly. Thereafter, and until the completion of the lasting operation, the bar 68 is locked against movement transverselyflof the ma chine and shoe. A yielding qualityis however impartedto the downward compressing movements of the wipersby the provision of springs 112 coiled around rods 104. Confining nuts 114 at the lower ends of the rods 104 are adapted to be turned to adjust the tension of the springs and stop nuts 116 are positioned above plate 108 to limit downward movement of the latches and insure their release from the bar 68 at the proper stage in the cycle of operations of the machine. The springs 112 normally tend to draw the barGS downwardly in the guides 70 but permit it against the tension of saidsprings sufiiciently to permit ofthe full extent oit'the upward movement of the wipers and to impart a yielding quality to their downward movement.

In order to accommodate theaction of the w'pcrs to the plane of the last forepart irrespective of the angular position of the shoe and. last, the wiper carrier 24, as before stated, is journaled at its ends in the iilUCliS 80 and 46. This mounting of the bar 24 permits the said bar and thewipers to turn freely about the longitudinal axis of the bar and thereby allows the wipers to accon'nnodate themselves to the roll of the last. I I

For supporting the shoe and last in position for the operation of the lasting device, a toe rest and a heel. su jiport are provided. prise a pad 118 (Fig. 1) of a suitable shape to lit the toe of the shoe upper and secured to a plate 1.20 fixed upon the upper end of a post 121 as by the straps The post 120 is sup ivorted for vertical adjustment in a bearing block rising from an extension of the toe hea'dfi. The lower end of the post 120 rests 120. The screw 126 is threadedinto the bearing 12.4 and is arranged to be turned by means of a hand. wheel 128 to adjust the post 120 and pad 118 to any desired height.

For supporting the heel end of the last a to be raised slightly The toe rest may conveniently comupon. an adjusting screw last pin 130 (Fig. 1) is pivoted at 132. to the upper end of a post 134. The post 134 is supported for vertical movement in a bearing block 136 secured by bolts to the bed of the machine. The lower end of the post 134 rests upon a rounded cam face formed upon the upper end of an operating lever 138 fulcrumed by means of a pivot pin 140 carried in a yoke 142 slidingly mounted on bracket arms 144 depending from the bed 2. The yoke 142 rests upon a set screw 145. Adjustment of the said screw 145 operates to adjust the yoke 142 vertically on the arms 144 to move the post 134 up or down to regulate the normal or inoperative position of the last pin 130. A coiled spring 146 secured at one end to a hook on a bar 148 depending from the bearing block 136 and fixed at its other end to a hook on the lever 138 normallytends to raise the outer end of said lever and thereby to maintain the post 134 and pin 130 in lowermost or inoperative position. For jacking the shoe the post 134 and pin 130 are raised into operative position by lowering the end of lever 138 against the tension of the spring. In order that the heel post and last pin may be secured in a raised or operative position the depending bar 148 is notched and a beveled plate 149 secured to the lever 138 is adapted to be brought into engagement with one or another the bar 148 thereby locking the lever 138 in any desired position.

In some work it is desirable to employ a hold down to clamp the shoe and last upon theirsupporting means. For this purpose preferably a lever 150 (Fig. 1) is fulcrumed at 152 upon an upright standard 154 secured to the bed 2 of the machine. The free end of. the lever 150 is adapted to engage the forepart of the inner sole, when the shoe is jacked in position for the operation of the lasting devices to hold the shoe and last firmly upon their supports. -The other end of lever 150 is pivotally connected to a treadle rod 156 (Fig. 1) arranged to be operated by a treadle 158 pivoted upon a stand 160 resting upon the floor. Downward movement of treadle 158 operating to raise the rod 156 and the arm of the lever 150 connected thereto, causes the free, end of lever 150 to be lowered into engagement with the inner sole of the shoe, as shown in Fig. 2 while the lever 150 is returned to its inoperative position by upward movement or". the treadle 158. Conveniently, the stand 160 has an upright rising therefrom and provided with notched teeth 162 adapted to be engaged by the treadle 158 to permit the hold down to bebrought into engagement with the shoe with any suitable pressure and then looked in such engagement.

To cooperate with the toe wipers in the of the ratchet teeth on lasting operation I have devised an imupper material at the end I the upper proved retarding device, best shown in Figs. 3 and 4, which comprises a central member 164 and a corner plate 166. The central member 164 preferably comprises a curved blade adapted to bear with its relatively thin edge upon the inner side of'the Outstanding of. the toe to hold upon the wipers. The corner member 166 preferably comprises a relatively wide plate adapted to extend transversely of the shoe to bear with its ends upon the upper materials at the corners of the toe'and carried at the lower end'of a rod 167 adjustably secured to a lever'170. The blade member 164 is secured to. the lower 'end of a post 168 which extends upwardly through a hole in the lever 170. The post 168 has fixed to it above the lever 170 a washer 172 and the upper end of the said post is confined by a set screw in a bar 17 4, the front end of which embraces a pin 176 rising from the lever 170. The lever 170 has its free end 17 8 suitably formed as an operating handle, and is pivoted at its other end to the rectangular portion 26 of the wiper carrier bar 24 1). The lever 170 is thus permitted to be swung upward when not in use, shouldered portions 180 (Fig. 1) sustaining the lever in its said inoperative position. Preferably, a spring 182 encircles the post 168, the said spring 'being confined between the lever 170 and a washer on the post 168 above the blade 164. The member 164 is thus brought to bear upon the upper with spring pressure, the spring serving automatically to increase the amount of pressure with which the blade 164 clamps the upper upon the wipers.

In the use of the above ing device, upon depression of the handle 118 and lever 170, the blade 164 engages the upper at the end of the toe and holds it yieldingly uponthe wipers during the updraw, the path of the blade 164 during the updraw and overwipe being indicated by the arrow in Fig. 3. The corner plate 166 acts by rigid engagement with the upper at the corners of the toe as a stop for limiting the downward movement of the blade 164.

During the updraw, the upward movement of the wipers forces the blade 164 upwardly against the tension of the spring 182 with the result that the clamping pressure of the blade 164 is thereby automatically increasec as the updraw progresses. The member 164 remains in engagement with the upper during the closing or overwiping movement of the wipers but does not of course partake of this closing movement. Consequently the wipers have a forward drawing effect which results in drafting the vamp forwardly along the sides of the shoe. It should also be noticed that the curvature of with the wipers.

described retard- I the member 164 is considerably less than 5 that of the end of the toe, as clearly shown in Fig. 2. As a result, the said member has a spreading action upon the upper which materially assists the drafting of the vamp along the sides by the wipers during their upward movement. The corner member 166 is lifted by the wipers in the updraw and continues to hold the upper upon the wipers during the overwipe/ By reason of the mounting of this supporting lever 170 upon the bar 24 the corner member is advanced The wi )ers however, as they are moved forwardly, swing inwardly. This inward swinging movement has a sufiicient backward component to produce an undesirable fullness at the sides of the toe. The member 166 does not partake of this backward movement, and consequently it has a retarding action during the overwipe which'serves 'materially to reduce the fullness at the sides of the toe. The corner member 166 also projects outwardly at either end beyond the edges of the shoe so that it has a substantial spreading action which aids the above described side drafting of the vamp.

The heel lasting mechanism is in most respects like the toe lasting mechanism hereinbefore described and is substantially similar in its mode of operation. The heel Wipers 184 (Fig. 5) are pivoted at 186 to the forward end of a carrier bar 188'mounted for upward tipping and forward bodily movements in precisely the same way inwhich bar 24 of the toe lasting mechanism is supported. Supporting ar1ns190 secured to the bar 188 at their rear ends have a hearing at their free ends between arms 192 of wiper closing levers 194 and under plates bolted to the said arms. The wiper closing levers 194 have at their rear ends cam slots 196 in whichlie cam rolls 198 on a cam roll carryingbar 200 extending transversely of the machine through a slot in the bar 188 and restrained from movement longitudinally of the machine by uprightguides 202* on the heel head 8.

The cam roll carrying bar 200 is however fixed against movement transversely of the machine and shoe by stops 204, the substantial uniformity of the heel portions. of shoes with respect to the direction of their median lines rendering it unnecessary that the bar 200 should have the equalizing function of the cam roll carrying bar 68 of the toe lastmg mechanism. The carrier bar 188 and the .carrier wipers 184 are actuated to engage on the said link, the bracket 212 being substantially like the bracket 88 of the toe lasting mechanism. p

The heel supporting band 214i has its ends passed around the free ends of links 216 (Fig. 5) pivoted to plates 218 on the wiper closing levers 194, the saidends of the band being securedto springs 220 hooked at their outer ends to the arms 192. These springs tend to draw the ends of the heel supporting band outwardly, thereby causing the band to adapt itself to embrace snugly heels of varying contours and sizes.

In the use of the machine herein shown and described as embodying myinvention, the last with the shoe thereon is acked with the toe resting upon the toe rest pad 118, and the heel part supported by the last pin 130. The hold down is then brought into firm engagement with the inner sole of the shoe. The toe wipers are next adj usted if necessary, to accommodate themselvesto the spring of the last by passing the pivot pin 32 through the proper pair of holes 34, and the eccentric 80 is adjusted lengthwise of the slot 19% to adapt the throw of the wipers to the width of the sole, After this preliminary adjustment the handle 86 is moved from its initial position through an are re versely to its general direction of rotation as indicated by the arrow Fig. 1 andsubstantially to the position shown in Fig, 1

for initially positioning the wipers as here-- tofore explained. Thismovementof the handle 86 operates the eccentric 80 to engage the part 90 of the supporting link 50 therebyinducing forward movement of the bar at and wipers 54. By this movement the wipers, which lie, in their initial position, below the plane of the shoe bottom, are partially closed and, through the equalizing movement of the cam roll carryingbar 68, the wipers arepositioned relatively to the adjacent edges of the last. The upper around the toe is then drawn upwardly over the wipers, usually by hand grippers, and the retarder is swung downwardly to clamp the upper uponthe wipers bothat the end and at the corners of the toe, the-plate 166 limiting the movement of the yielding member nu. CF16 eccentric 80 having been returned to its initial position by rotation of the handle 86 in the direction of the arrow Fig. 1, during which movement the eccentric is brought to bear against the arm of the bracket 88 thereby opening the wipers again, the handle 86 is given further continued movement in the direction of the arrow for initiating the updraw. This movement of the handle 86 causes the eccentric 80 to engage the underside of the part 26 ofthe carrier 2% whereby the carrier and wipers are lifted upwardly. During the first part of the updraw, the cam roll carrying bar 68 is lifted suiiiciently tobe locked in its adj usted the same direction, the eccentric 80 engages the part 90 of the link 50 thereby causing the carrier 2% and wipers 54 to be advanced for the overwipe. The wipers 54: are then swung inwardly for over-wiping the upper into lasted position, the retarder, which is all the time held firmly upon the upper, serving, as hereinbefore explained, to facilitate the lasting action of the wipers. After the completion of the overwipe, continued rotation of the handle 86 and eccentric 80 in the same direction results in bringing the eccentric to bear against the curved bottom portion of the bracket 88, whereby the carrier 24 is tipped downwardly about its axis andthe wipers are positively pulled down wardly upon the overlasted upper for compressing and compacting it in lasted position. l Vith the lasting devices held in this position, the operator secures the upper in its lasted position by binding wire or other temporary fastenings and the handle 86 is then returned to its initial position, the wipers being lowered, retracted, and opened, and the lasting instrumentalities being then ready for another operation. The lasting of the heel proceeds in a similar fashion, the heel wiper carrying bar being, actuated through its operating cam to advance the wipers for engaging the upperaround the heel and carrying the upper forwardly and inwardly into position to receive permanent tacks.

It should be understood that the foregoing is merely a description of one convenient embodiment of my invention, shown and described simply by way, of illustration, and that I. do not thereby limit myself to the precise details of construction herein set forth, since many changes and modifications thereof, such as will readily occur to those skilled in the art, may obviously be made without departing scope of my, invention.
